Shorter mothers have shorter pregnancies, smaller babies, and higher risk for a preterm birth. New research has found that a mother's height directly influences her risk for preterm birth.
Conclusion: Short women with heights up to 150 cm are at risk of failing spontaneous vaginal delivery and should be referred to hospitals where labor could be closely monitored and cesarean section performed if necessary.
However, the authors of a Swedish study among 952 630 unselected pregnant women whose gestational length was estimated by ultrasound in early second trimester, reported that unadjusted mean gestational length was 2 days shorter in mothers of short stature (< 160 cm) compared to those who were taller than 160 cm [5].
Your Height
Whether you're tall or short can affect your bump. Tall pregnant women with long torsos tend to carry in front since the baby has room to push up, while short pregnant women tend to have a belly that pushes outward and is a bit more spread out.
You'll likely notice the first signs of a bump early in the second trimester, between weeks 12 and 16. You might start showing closer to 12 weeks if you are a person of lower weight with a smaller midsection, and closer to 16 weeks if you're a person with more weight.
August 2015 research published in the journal PLOS Medicine finds that not only do shorter women have babies with lower birth weights and lengths—but the duration of their pregnancy is actually shorter as well. This means that being shorter in stature may very well be a risk factor for preterm birth.
Petite women can absolutely have safe vaginal births; body size is not the only factor that weighs into a woman's ability to safely deliver vaginally. Watch OB/GYN specialist Evelyn Minaya, MD, dispel this myth and share a relevant anecdote.
Background: Maternal height has been reported as an obstetric risk factor, since short maternal stature may be associated with an increased incidence of obstructed labour due to cephalopelvic disproportion.
Having a high BMI can harm fertility by inhibiting regular ovulation. Even in women who regularly ovulate, the higher the BMI , the longer it may take to become pregnant. Some research also suggests that a higher BMI is associated with an increased risk of unsuccessful in vitro fertilization (IVF).
The ideal BMI for getting pregnant is between 18.5 and 24.9. This is known as the healthy range. If you have a high BMI, bringing it closer to the healthy range before trying for a baby will help you get pregnant as well as improving the health of your future pregnancy and child.
women in the normal weight range (BMI of 18.5-24.9) are recommended to put on between 37-54 lbs (16.8-24.5kg) women who are overweight (BMI between 25 and 29.9) are recommended to put on between 31-50 lbs (14.1-22.7kg)
Maternal height is a highly used anthropometric parameter that impacts pregnancy outcomes [1]. Short maternal stature has been related to intrauterine growth restriction, low birth weight, and small for gestational age (SGA) that appears in the ultrasound estimated fetal weight in the third trimester [2-3].
The genetics of height
As a general rule of thumb, your height can be predicted based on how tall your parents are. If they are tall or short, then your own height is said to end up somewhere based on the average heights between your two parents.
Maternal physical and social characteristics that can contribute to a high-risk pregnancy include: age younger than 15 years and older than 35 years. pre-pregnancy weight under 100 lbs (45 kg) or obesity. height under 5 ft (1.5 m)
Being overweight, obese or underweight can affect a woman's fertility. Obesity can lower fertility in men. You have a greater chance of getting pregnant and having a healthy baby if you are close to a healthy weight. A small weight loss can improve fertility and pregnancy health.
Wider hips provide plenty of room for a baby to pass through the pelvic bones. But hip size isn't the only factor that affects your birth experience. The truth is, some women with so-called childbearing hips have had difficult deliveries, and some women with narrower pelvic shapes have had easier births.
The narrower shape of the android pelvis can make labor difficult because the baby might move more slowly through the birth canal. Some pregnant women with an android pelvis may require a C-section.
Mothers' and fathers' birthweights are each significantly related to their infants' birthweight, even after control for 31 potentially confounding variables. The relationship is stronger for mothers and daughters than for other parent-offspring pairs.
Background: Both birth length and birth weight are associated with height in adulthood and may have independent contributions to adult body size, but the effects of gestational age on these associations have not been fully evaluated.
The unborn baby spends around 38 weeks in the uterus, but the average length of pregnancy, or gestation, is counted at 40 weeks. Pregnancy is counted from the first day of the woman's last period, not the date of conception which generally occurs two weeks later.
If you're overweight, doctors advise losing the extra pounds before you conceive, if possible. Going into your pregnancy overweight means you could put your own health and your baby's health at risk, and potentially set your child up for a lifetime of health issues.
